Abstract
Hypercalcemia during pregnancy is a risk for adverse maternal and fetal consequences. Although primary hyperparathyroidism is by far the most common etiology of hypercalcemia in pregnancy, an array of other etiologies of hypercalcemia associated with pregnancy and lactation have been described. Parathyroidectomy continues to be the preferred treatment for primary hyperparathyroidism. Medical management options are limited.

[PMID: 38485054 DOI: 10.1016/j.ajogmf.2024.101348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 03/06/2024] [Accepted: 03/07/2024] [Indexed: 04/01/2024]
Abstract
BACKGROUND Hypertensive disorders of pregnancy are a leading cause of perinatal morbidity, and timely treatment of severely elevated blood pressure is recommended to prevent serious sequelae. In acute hypertension marked by increased blood volume, it is unknown whether diuretics used as an adjunct to antihypertensive medications lead to more effective blood pressure control. OBJECTIVE This study aimed to evaluate whether the addition of intravenous furosemide to first-line antihypertensive agents reduces systolic blood pressure in acute-onset, severe antenatal hypertension with wide (≥60 mm Hg) pulse pressure. STUDY DESIGN In this double-blinded randomized trial, participants received 40 mg of intravenous furosemide or placebo in addition to a first-line antihypertensive agent. The primary outcome was mean systolic blood pressure during the first hour after intervention. Secondary outcomes included corresponding diastolic blood pressure; systolic blood pressure, diastolic blood pressure, and pulse pressure at 2 hours after intervention; total reduction from qualifying blood pressure; duration of blood pressure control; need for additional antihypertensive doses within 1 hour; and electrolytes and urine output. A sample size of 35 participants per group was planned to detect a 15-mm Hg difference in blood pressure. RESULTS Between January 2021 and March 2022, 65 individuals were randomized: 33 to furosemide and 32 to placebo. Baseline characteristics were similar between the groups. There was no difference in the primary outcome of mean 1-hour systolic blood pressure (147 [14.8] vs 152 [13.8] mm Hg; P=.200). We found a reduction in 2-hour systolic blood pressure (139 [18.5] vs 154 [18.4] mm Hg; P=.007) and a decrease in 2-hour pulse pressure (55 [12.5] vs 67 [15.1]; P=.003) in the furosemide group. Subgroup analysis according to hypertension type showed a significant reduction in 2-hour systolic blood pressure and 2-hour pulse pressure among patients with new-onset hypertension, but not among those with preexisting hypertension. Urine output was greater in the furosemide group, with no difference in electrolytes and creatinine before and after intervention. CONCLUSION Intravenous furosemide in conjunction with a first-line antihypertensive agent did not significantly reduce systolic blood pressure in the first hour after administration. However, both systolic blood pressure and pulse pressure at 2 hours were decreased in the furosemide group. These findings suggest that a 1-time dose of intravenous furosemide is a reasonable adjunct to achieve blood pressure control, particularly in patients in whom increased volume is suspected.

Abstract
The majority of women with repaired tetralogy of Fallot are able to tolerate pregnancy with a low risk of cardiovascular events. However, proactive contraceptive advice, prepregnancy counselling, and care by a pregnancy heart team with expertise in congenital heart disease are key to ensuring a good outcome for mother and baby. Maternal and fetal risks are increased in the presence of severe valvular stenosis, poorly tolerated arrhythmia, significant ventricular dysfunction, and cyanosis. It is unusual to see cyanotic adults with tetralogy of Fallot, whether unoperated or shunt palliated; pregnancy risks are greatly reduced by completing their repair before pregnancy is undertaken. The multidisciplinary pregnancy heart team should make a risk-stratified pregnancy care plan using a combination of published scoring systems and an individualized assessment of the patient's comorbidities. Low-risk patients may have the majority of their care and give birth in local units, whereas those at high risk should be managed and give birth in a tertiary centre with high-level expertise and intensive care facilities. Age-appropriate conversations about future childbearing and safe and reliable contraception should be part of routine follow-up from teenage years, so that women with tetralogy of Fallot can control their own fertility and make informed decisions about having children.

Abstract
Primary hyperparathyroidism in pregnancy is a rare disease that can have detrimental effects on both maternal and fetal/neonatal outcomes. The physiological changes that occur during pregnancy can complicate the diagnosis, imaging examinations, and treatment of this disorder. To enhance our understanding and management of primary hyperparathyroidism in pregnancy, experts from various fields, including endocrinology, obstetrics, surgery, ultrasonography, nuclear medicine, pediatrics, nephrology, and general practice in China, collaborated to develop a consensus addressing the critical aspects of the diagnosis and treatment of primary hyperparathyroidism in pregnancy with a multidisciplinary team approach. This consensus provides valuable guidance for healthcare professionals in managing this condition, ultimately improving outcomes for both mothers and their babies.

Abstract
PURPOSE OF REVIEW Cardiovascular disease is the leading cause of maternal mortality in the USA. All cardiovascular care providers should have a foundational knowledge on the management of pregnant individuals with heart disease. This focused review touches on several key cardio-obstetric themes. RECENT FINDINGS Many individuals with cardiovascular disease can safely undergo pregnancy, but should have counseling preconception to optimize cardiac status. There are several cardiovascular conditions that are high risk for maternal mortality and morbidity. These individuals should be adequately counseled preconception and offered reliable birth control. The approach to a high-risk pregnant patient with cardiac disease is best managed by a multidisciplinary team to address potential maternal and fetal complications. Identification of at risk individuals can be estimated preconception with several risk scores. The development of risk scores to stratify and identify those at elevated risk during pregnancy is an area of continued research and development.

Abstract
OBJECTIVE We provide succinct, evidence-based and/or consensus-based best practice guidance for the cardiac care of children living with Duchenne muscular dystrophy (DMD) as well as recommendations for screening and management of female carriers of mutations in the DMD-gene. METHODS Initiated by an expert working group of UK-based cardiologists, neuromuscular clinicians and DMD-patient representatives, draft guidelines were created based on published evidence, current practice and expert opinion. After wider consultation with UK-cardiologists, consensus was reached on these best-practice recommendations for cardiac care in DMD. RESULTS The resulting recommendations are presented in the form of a succinct care pathway flow chart with brief justification. The guidance signposts evidence on which they are based and acknowledges where there have been differences in opinion. Guidelines for cardiac care of patients with more advanced cardiac dystrophinopathy at any age have also been considered, based on the previous published work of Quinlivan et al and are presented here in a similar format. The recommendations have been endorsed by the British Cardiovascular Society. CONCLUSION These guidelines provide succinct, reasoned recommendations for all those managing paediatric patients with early or advanced stages of cardiomyopathy as well as females with cardiac dystrophinopathy. The hope is that this will result in more uniform delivery of high standards of care for children with cardiac dystrophinopathy, so improving heart health into adulthood through timely earlier interventions across the UK.

The Risk for Neonatal Hypoglycemia and Bradycardia after Beta-Blocker Use during Pregnancy or Lactation: A Systematic Review and Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19159616.

Abstract
Beta-blockers are often used during pregnancy to treat cardiovascular diseases. The described neonatal side effects of maternal beta-blocker use are hypoglycemia and bradycardia, but the evidence base for these is yet to be evaluated comprehensively. Hence, this systematic review and meta-analysis was performed to evaluate the potential increased risk for hypoglycemia and bradycardia in neonates exposed to beta-blockers in utero or during lactation. A systematic search of English-language human studies was conducted until 21 April 2021. Both observational studies and randomized controlled trials investigating hypoglycemia and/or bradycardia in neonates following beta-blocker exposure during pregnancy and lactation were included. All articles were screened by two authors independently and eligible studies were included. Pair-wise and proportion-based meta-analysis was conducted and the certainty of evidence (CoE) was performed by standard methodologies. Of the 1.043 screened articles, 55 were included in this systematic review. Our meta-analysis showed a probable risk of hypoglycemia (CoE—Moderate) and possible risk of bradycardia (CoE—Low) in neonates upon fetal beta-blocker exposure. Therefore, we suggest the monitoring of glucose levels in exposed neonates until 24 h after birth. Due to the limited clinical implication, monitoring of the heart rate could be considered for 24 h. We call for future studies to substantiate our findings.

Abstract
PURPOSE OF REVIEW The intent of this review is to provide an update in polypharmacy in older adults and women with a focus on common determinants and strategies to mitigate polypharmacy. RECENT FINDINGS Polypharmacy is becoming a critical focus in the management of cardiovascular diseases. It may emerge unintentionally while managing multimorbidity in older adults or in the vulnerable subgroup of patients, such as pregnant and lactating females. Clinicians should utilize several approaches such as deprescribing, sex-specific risk assessment, and encouraging healthy lifestyle to minimize inappropriate and unnecessary use of medications. A shared decision-making model along with coordination and collaboration among healthcare providers should be utilized in the selection and management of pharmacotherapies.

Abstract
Only a few studies describe the pathophysiology and outcomes of dilated cardiomyopathy (DCM) in pregnancy, which the authors aim to review here. DCM causes enlargement of the ventricles and reduced systolic function. Fluid overload and raised cardiac output in pregnancy may contribute to cardiac complications that lead to cardiac remodeling and heart failure, a common cause of maternal mortality. The risk of cardiac complications is higher in women with New York Heart Association class III and IV. Fetal and neonatal complications are common with coexisting obstetric risk factors. Hence, prepregnancy counseling and a multi-disciplinary approach are essential. Renin-angiotensin-aldosterone system blockers prevent cardiac remodeling but are teratogenic. Drugs, such as β-blockers to control cardiac remodeling, thiazide diuretics to reduce preload, hydralazine and nitrates to reduce afterload and digoxin to increase inotropy, are safe and should be used to manage DCM in pregnancy.

Abstract
Hypercalcemic disorders are rare in pregnant women and are usually due to primary hyperparathyroidism. Clinical manifestations of hypercalcemia are nonspecific and can be masked by the physiologic changes of pregnancy. Furthermore, routine antenatal screening does not include serum calcium measurement and a hypercalcemia diagnosis may therefore be delayed until term or even after delivery. Timely recognition and appropriate interventions are essential to decrease maternal and fetal complications. Conservative measures are appropriate in the presence of mild hypercalcemia. Parathyroidectomy remains the mainstay of treatment for primary hyperparathyroidism with significant hypercalcemia not responding to conservative measures.

Abstract
INTRODUCTION Hypertensive disorders of pregnancy (HDP) are rising in prevalence, and increase risk of adverse maternal and fetal outcomes. Physiologic changes occur during pregnancy that alter drug pharmacokinetics. However, antihypertensive drugs lack pregnancy-specific dosing recommendations due to critical knowledge gaps surrounding the extent of gestational changes in antihypertensive drug pharmacokinetics and underlying mechanisms. AREAS COVERED This review (1) summarizes currently recommended medications and dosing strategies for non-emergent HDP treatment, (2) reviews and synthesizes existing literature identified via a comprehensive Pubmed search evaluating gestational changes in the maternal pharmacokinetics of commonly prescribed HDP drugs (notably labetalol and nifedipine), and (3) offers insight into the metabolism and clearance mechanisms underlying altered HDP drug pharmacokinetics during pregnancy. Remaining knowledge gaps and future research directions are summarized. EXPERT OPINION A series of small pharmacokinetic studies illustrate higher oral clearance of labetalol and nifedipine during pregnancy. Pharmacokinetic modeling and preclinical studies suggest these effects are likely due to pregnancy-associated increases in hepatic UGT1A1- and CYP3A4-mediated first-pass metabolism and lower bioavailability. Accordingly, higher and/or more frequent doses may be needed to lower blood pressure during pregnancy. Future research is needed to address various evidence gaps and inform the development of more precise antihypertensive drug dosing strategies.

Abstract
The developmental origins of health and disease (DOHaD) is a concept linking pre- and early postnatal exposures to environmental influences with long-term health outcomes and susceptibility to disease. It has provided a new perspective on the etiology and evolution of chronic disease risk, and as such is a classic example of a paradigm shift. What first emerged as the 'fetal origins of disease', the evolution of the DOHaD conceptual framework is a storied one in which preclinical studies played an important role. With its potential clinical applications of DOHaD, there is increasing desire to leverage this growing body of preclinical work to improve health outcomes in populations all over the world. In this review, we provide a perspective on the values and limitations of preclinical research, and the challenges that impede its translation. The review focuses largely on the developmental programming of cardiovascular function and begins with a brief discussion on the emergence of the 'Barker hypothesis', and its subsequent evolution into the more-encompassing DOHaD framework. We then discuss some fundamental pathophysiological processes by which developmental programming may occur, and attempt to define these as 'instigator' and 'effector' mechanisms, according to their role in early adversity. We conclude with a brief discussion of some notable challenges that hinder the translation of this preclinical work.

Abstract
Cardiac disease is a leading cause of morbidity and mortality in pregnant women. An increased prevalence of the cardiovascular disease has been found in women of childbearing age, in which the responsibility of the treating physician extends to the mother and to the unborn fetus. As a result, care of these high-risk pregnant women with cardiovascular disease including those with congenital heart disease (CHD) require a team approach including specialists in maternal-fetal medicine, adult congenital cardiology, and obstetrical anesthesia. The human body undergoes significant amounts of physiological changes during this period of time and the underlying cardiac disease can affect both the mother and the fetus. Today, most female children born with CHD will reach childbearing age. For many women with complex CHD, carrying a pregnancy has a moderate to high risk for both the mother and her fetus. This chapter will review the epidemiology, risk factors, clinical presentation including common signs and symptoms, physiological changes in pregnancy, and the medical approach including cardiac medications, percutaneous interventions, and surgical procedures for pregnant women with CHD.

Abstract
Andersen-Tawil syndrome (ATS) is a rare channelopathy, sometimes referred to as long QT syndrome type 7. ATS is an autosomal dominant disease predominantly caused by mutations in the KCNJ2 gene. Patients with ATS present with episodes of muscle weakness, arrythmias, including prolonged QT intervals, and various skeletal abnormalities. Unlike other channelopathies, ATS has a relatively mild clinical course and low risk of sudden cardiac death. In this study, we describe a female patient with typical symptoms of ATS with the addition of unusually severe arrhythmias. Extensive DNA testing was performed to find the possible cause of this unique presentation. In addition to a known mutation in KCNJ2, the patient carried a variant in KCNH2 The combination of genetic variants may lead to the severe clinical manifestation of ATS. Additional genetic information allowed accurate genetic counselling to be provided to the patient.

Abstract
The third trimester of pregnancy is related to physiological changes that can modify the process of absorption, distribution, metabolism, and excretion and, consequently, the efficacy and toxicity of drugs. However, little is known about furosemide pharmacokinetics and placental transfer in pregnancy. This study evaluated the maternal-fetal pharmacokinetics and distribution to amniotic fluid of furosemide in hypertensive parturient women under cesarean section. Twelve hypertensive parturient women under methyldopa (250 mg/8 h) and/or pindolol (10 mg/12 h) treatment received a 40-mg single oral dose of furosemide 1 to 10 hours before delivery by cesarean section. Blood and urine samples were collected for 12 hours after furosemide administration. At delivery, samples were obtained from maternal and umbilical cord blood (n = 8) to assess the transplacental transfer. Amniotic fluid (n = 4) was collected at the time of delivery. The following furosemide pharmacokinetic parameters were obtained as median (interquartile range): Cmax , 403 ng/mL (229 to 715 ng/mL); Tmax , 2.00 hours (1.50 to 4.83 hours); elimination half-life (t1/2 ), 2.50 hours (1.77 to 2.97 hours); AUC0-12 h , 1366 ng⋅h/mL (927 to 2531 ng⋅h/mL); AUC0-∞ , 1580 ng⋅h/mL (1270 to 2881 ng⋅h/mL); CL/F 25.3 L/h (13.8 to 31.4 L/h); CLR, 2.50 L/h (1.77 to 2.97 L/h); CLNR, 22.7 L/h (12.1 to 25.6 L/h); and Vd /F 82.8 L (34.4 to 173 L). The transplacental transfer of furosemide was 0.43 (0.10 to 0.73), and the amniotic fluid concentration was 11.0 ng/mL (5.51 to 14.6 ng/mL). From a clinical point of view, these results suggest that substrates of uridine diphosphate-glucuronosyltransferase isoenzymes such as furosemide may have increased clearance during pregnancy and could require dose adjustment in this population.
